Description

The two films you see in this clip are known as the 1950 "Mariana UFO Film" (Montana Film) filmed near Great Falls, MT and the 1952 "Newhouse UFO Film" (Utah Film) filmed near Tremonton, UT.

These were first released in the 1956 documentary, Unidentified Flying Objects: The True Story of Flying Saucers (https://youtu.be/lAAejzH1iww?si=csY95nAltNZOHFFO).

In that same documentary, you can watch both Nick Mariana & Delbert Newhouse give their first hand accounts of their sightings.

Both cases were analyzed by the Photo Reconnaissance Lab, Wright-Patterson AFB and by the US Navy Photo Interpretation Center. Both were classified as "unidentified" for Project Blue Book (https://www.archives.gov/research/military/air-force/ufos).

Here is an interesting article from the Great Falls Museum about the Mariana incident (https://www.greatfallshistorymuseum.org/blog/the-mariana-ufo-great-fa…).
